If that is true does the cleaning up bit just come from the exhaust?

You are right. If you burn a litre of diesel you give off the same amount of CO2 no matter what. The difference is that a modern turbo diesel makes far more power and torque from each litre of diesel it burns than a 1980s diesel. In addition modern diesels reduce emissions of particulate matter, NOx and other bad stuff via DPFs, urea injection etc
